Reply to comment by diogenes_shadow in Did you know it will still take 46 billion years to cross the universe at the speed of light? 65 mph = 4.8 * 10^17 years! by NotAndroid545

Yeah, galaxies 18b light years away have space expanding between us and them at a rate thats faster than the speed of light without breaking the speed of light, its the space thats changing. There’s so much space between here and there that the expansion causes the effect, its not a speed limit issue.

Reply to Which theory about aliens is the most likely? by [deleted]

The universe is huge and old, the simple fact is Earth was likely given life via pansperma, and aliens most likely have been visiting for hundreds of millions of years.

The sun is only like 5 billion years old while earth is 4.5b. The universe Is 13b years old and likely has has had a trillion different species come and go. The number that could create spacecraft have probably been in the hundreds.
